It is an object of this invention to provide double doors for railway house cars so related and associated with the cars that substantial doors together reduced.

A further object is to provide novel abutment Other objects of the invention will become clear as the description thereof proceeds.

In the drawings forming part of this speoication:

Fig. l is a fragmentary elevation illustrating the upper adjacent portions of double doors of a railway house car and their relationship with the car side.

Fig. 2 is a vertical section taken on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary elevation illustrating ably reinforced by means of upper and lower and I5. The front vertical margin of the main door 0 is reinforced by means of a vertical backing plate l1 and a channel shaped stilening member I8. The front verof the door and cooperating With the member I9 to provide a recess 2| which receives the front edge of the main door when the doors are in closed position. The upper margin of each of the doors is reinforced by means of an angle with a substantially J-shaped header to the depending leg 25 of a substantially Z- shaped side plate 26. The upper margins of the Z-shaped member to the depending leg 29 of the door retainer 21. The lower margin of each of the doors l0 and act'er may be employed. y y l y mmon in doubledoor construction to It is co utilize locking means extending across the meet- Any desired locking for this purpose. n Y Y In Order to obtain substantial unityof moveing vertical leg 45 of the 'disposition the vertical leg 45 is order to properly dispose :through 90 y 43 into proper engagement thereby relieve y ward corner of ing Ais secured to 1 margins of the form Iinner and end wall 55. By this construction, flange 45 is permitted to enter 2 ment of the doors in a plane parallel to the car side when the cars to which they are applied are subjected to impact so that the locking means employed for the doors is relieved of stress injurious to said means, the considered embodiment of the invention utilizes a substantially Z- shaped member 33 fastened to the depending flange 25 of the side plate 25. The web 34 of this member extends outwardly below the side plate and J-shaped header 24 so that the flange S thereof lies in proximity to the upper portions of the main and auxiliary doors at their meeting edges for the purpose of excluding both direct and reected light from entering the car at the indicated point. The upstanding flange 35 of the Z-shaped member by means of which fastening of the member to the side plate is secured is provided with an inwardly projecting indenture 31. Cooperating with the indenture 31 is a vertical flange 58 formed on a member 39 secured to the upper margin of the Vauxiliary door post Z5. By virtue of this cooperation thev auxiliary door is drawn inwardly toward the car side as the door approaches its final closed position.v In this position it will be observed that the vertical flange 33 lies inwardly of the indenture 31 and is free for movement in a plane parallel to the car side. A

The purpose hereinabove set forth is secured at the lower margins of the doors as well. To this end in the embodiment considered a member 45 is fastened to the reinforcement 4| for the side sill 42 of the car underframe. The mem- A ber 45 is rolled and is Z-shaped in section and embodies the depending attaching flange 43, the

outwardly extending web 44 and the vertical iiange 45 which extends above the door track 32 as illustrated in Fig. 4 of the drawings. The upstanding flange 45 lies outwardly of the dependtrack and to secure this cated at taching flange 43 is cope so as to bring thereto. It is preferred that the web 44 be welded to the vertical 'flange 45 of the track around the cope 41 therel Vin as indicated at 48 so as to cause the track to the member 40 and fastening the mem- 4| of such incident upon the means for the reinforcing channel absorb stresses ber 45 to stress.

The upstanding the member 40 flange 45 of Aserves as an abutment flange for limiting closing movement of the auxiliary door. Cooperating with the abutment flange for the purpose indicated is a casting 451 secured to the lower forthe auxiliary door li. This castboth the vertical and horizontal the door as by means of rivets 5i) and portions of the casting 5?. formed by means of the 53 and .54 and the the abutment the pocket 52 as the auxiliary door approaches its final closed position and limit closing movement of the door when elevated by engaging the end wall 55.

Rising from the web 44 of the m mber 40 is a lug 55 formed from a portion of the upstanding fiange of the Z-shaped member 45. As clearly shown in Figs. 3 and Thc'lower of a pocket outer spaced walls 5 of the drawings,.the lug is spaced from the abutment flange 45 and when the auxiliary door is in its closed and lowered position is received within a recess 51 formed in the casting 49 secured to the auxiliary door. In this position of the door the wall 58 of the lug is spaced a predetermined distance from the vertical wall 59 of the recess 51. It has been found by actual test that a spacing of 1/2 inch is satisfactory.

The lower forward corner of the main door lll carries a casting 55 provided with an outwardly extending flange 6i which extends across the abutment fiange 45 of the member 40 when the door is in closed position.

v In view of the construction at the lower margins of the doors hereinabove described unity of movement of the main and auxiliary doors in a plane parallel to the car side wall is obtained for the lower portions of the doors as well as pact to the cars to which the doors are applied the doors will rise in a plane parallel to the car side upon their front or rear lowercorners depending upon the direction of movement ofthe cars at the time that impact occurs. The construction hereinabove described does not prohibit this movement of the doors and it is to be observed particularly that the lug 5B permits such movement by reason of the space between its wall 58 and the wall 55 of the casting 49. The lug 58, however, is utilized to limit lthe opening movement of the auxiliary door when it is in lowered position and unlocked. It is desiredat times that loading or unloading of a car proceed through the main door opening only and that the auxiliary door remain closed. The lug 56 insures that the auxiliary door cannot be moved open accidentally a distance greater than the space between the walls 58 and 59.

The disposition of the ange 6i of the casting 60 secured to the lower forward corner of the main door relative to the abutment flange 45 insures against injury to the door postrand post strip and sealing strip commonly used upon doors of this character at their rear edges. Where impact occurs at the left hand end of the car as viewed in Fig. 3 of the drawings, the main door will rise about its lower forward corner and effect engagement between the post strip and sealing strip, tending to imposing severe stresses thereon. The cooperation between theflange 6iof the abutment flange 45 is effective to relieve-these parts of the indicated stresses. v

A modified form of the member 45 is illustrated in Figs. 6 and '1 of the drawings. The member there disclosed embodies a substantially channel shapedmember 52, the leg 63 of which is fastened to the channel reinforcement 4l. The web -64 of the member 52 extends outwardly and the outer leg 55 of this member extends downwardly and preferably outwardly from the web. A member. 65 has an attaching flange `B1 by means of which it is secured to the outer leg 55 of the channel member 62. The member 56 has a portion 68 which rises above the track 59 and extends through a cope 15 formed in the horizontal leg 1i of the track. The -portion 58 of the member 65 is preferably .welded to the track around the cope therein for thej purpose hereinbefore .set forth.

The upstanding portion 68 embodies anV abutment flange 12 which cooperates with a casting13 secured to the lower forward corner of the auxiliary door I l and of substantially the same construction as the casting 49 to limit closing. move- -:orient of the` auxiliary door. K The portion'h's,

position. The lug 14 thereby does not interfere with the movement of the door in a plane parallel to the oar side when the car is subjected to In this embodiment of the invention the main door I is Iprovided with a casting 6!) secured to the lower forward corner thereof for the purpose set forth in the :consideration of the rst embodiment of the invention.

Another form of the invention is illustrated in Figs. 8 and 9 of the drawings. In this embodiment a substantially channel shaped member I1 To this flange a member 82 is secured. The member 82 extends upwardly above the leg 'I9 through a cope 83 formed. in the leg. The portion of the member 82 which lies above the leg 19 provides an abutment flange 84 for limiting closing movement of the auxiliary door. The Ilange 84 is preferably welded to the leg 'I9 in the cope 83.

The leg 19 which is a continuation of the sections of the track 69, as clearly appears from Fig. 8 of the drawings, carries an upstanding lug 85. the leg 'FQ by `being cope 86 formed in the leg and welded to the leg around the cope.

A casting 8'! is secured to the lower forward Acorner of the auxiliary door and is provided with a pocket S8, the end Wall 89 of which engages the abutment ilange 84 to limit closing movement of the auxiliary door. The bracket 8l is provided with a recess 9B having a vertical wall Sl spaced from the upstanding lug 85 when the door is in closed position.

The casting 69 is provided at the corner of the main door. The member 39 secured to the upper portion of the auxiliary door post 20 and the Z-shaped member 33 fastened to the depending leg 25 of the side plate 26 are utilized with each of the embodiments of the invention illustrated in Figs. 6 to 9 inclusive.

The cooperation between the several :parts of the embodiments illustrated in Figs. 6 to 9 inclusive and the results obtained thereby are the same as described for the embodiment of the invention illustrated in Figs. l to inclusive.
